Speciation essay A species is a group of organisms that can breed together to produce fertile offspring. New species arise in two ways‚ hybridisation and polyploidy. Polyploidy is an increase in the number of sets of chromosomes. Hybridisation is the production of offspring from parents of two different species‚ this means though that the offspring is not fertile such a mule‚ a cross between a horse and a donkey‚ which is why hybridisation can only be explained in plants and not animals.

By taking the example of planets orbiting around the sun‚ the question rises that how do these devastating disasters occur? Floods occur in those areas which are closer to seas. Due to heavy rain‚ the sea water increases and spills out over the area with speed and destroying everything. Flash floods are another example of floods which occur suddenly

The Relationship of the Human Sciences to the Natural Sciences To a great extent‚ however‚ the human sciences do encompass natural facts and are based on knowledge of nature. If one were to imagine purely spiritual beings in a realm of persons which consisted only of such beings‚ then their coming-to-be‚ preservation‚ and development‚ as well as their extinction - whatever representations we may form of the background from which these beings appear and into which they disappear - would be dependent

organisms need other organisms for survival. An ecosystem is a community of living organisms. An ecosystem maintains an important balance in order for all organisms within the ecosystem to survive. The balance involves carbon‚ food‚ nitrogen‚ oxygen and water. The sun supplies the energy needed by ecosystems. Plants absorb the energy and use photosynthesis to convert it to sugar. There are nutrients in the air‚ soil and water that keep the ecosystem growing and balanced. A biome is a geographical

Why should humans be concerned with the extinction rate? This is an interesting question. Lets consider the fact that it begins by stating extinction is a natural selection process. This seems to stifle one side of this argument.The side of the argument that rallies humans to be concerned with the extinction rate and strive to preserve a representation

Natural Resources Resources on the Earth Biosphere: The whole combination of animals‚ plants and non-living beings which by their interaction make the planet earth a live and vibrant place is called biosphere. Biotic Components: Living things constitute the biotic component of the biosphere. Abiotic Components: The air‚ the water and the soil form the non-living or a biotic component of the biosphere. The air is called the hygrosphere‚ the water is hydrosphere and the soil is called lithosphere
